http://nagoya.apache.org/bugzilla/show_bug.cgi?id=21088 NullPointerException in RequestUtils.populate Summary: NullPointerException in RequestUtils.populate Product: Struts Version: 1.1RC2 Platform: PC OS/Version: Windows XP Status: NEW Severity: Normal Priority: Other Component: Utilities AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] Using the Orion application server 1.5.4 I get a null pointer exception in RequestUtils.populate if the session is new and I have gone directly to an action mapping in the URL. i.e. http://server:8080/home.do I'm using form based security, so I am correctly re-directed to my login page, but upon being re-directed back to the action home.do I receive the null pointer exception. I've debugged the code and the problem seems to be caused by a bug in Orion in that request.getParameterNames() on line 1161 in RequestUtils returns null rather than an empty enumeration. After a first page has been loaded getParameterNames() does correctly return an empty enumeration if no parameters are present. It would be very easy to put in a check for the variable names being null before attempting to iterate the collection. (line 1164) The stack trace of the error is: java.lang.NullPointerException at org.apache.struts.util.RequestUtils.populate(RequestUtils.java:1164) at org.apache.struts.action.RequestProcessor.processPopulate (RequestProcessor.java:821) at org.apache.struts.action.RequestProcessor.process (RequestProcessor.java:254) at org.apache.struts.action.ActionServlet.process (ActionServlet.java:1480) at org.apache.struts.action.ActionServlet.doPost (ActionServlet.java:524) at javax.servlet.http.HttpServlet.service(HttpServlet.java:211) at javax.servlet.http.HttpServlet.service(HttpServlet.java:309) at javax.servlet.http.HttpServlet.service(HttpServlet.java:336) at com.evermind[Orion/1.5.4 (build 10585)]._ie.doFilter(.:59) at filters.SetCharacterEncodingFilter.doFilter (SetCharacterEncodingFilter.java:150) at com.evermind[Orion/1.5.4 (build 10585)]._deb._lnc(.:380) at com.evermind[Orion/1.5.4 (build 10585)]._deb._wmb(.:170) at com.evermind[Orion/1.5.4 (build 10585)]._co._wbb(.:581) at com.evermind[Orion/1.5.4 (build 10585)]._co._fs(.:189) at com.evermind[Orion/1.5.4 (build 10585)]._bt.run(.:62) ============================== --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
